Original No. 1,429,911, dated September 19, 1922, Serial No. 575,607, filed July 17, 1922. Application for reissue filed November 21,

To all whom it may concern:

Be it known that I, h/IAX BorrMnn, acitizen ofthe Empireof Germany, residing at Chemnitz, Saxony, Germany, have invented a new. and useful Improvement in Wool- Combing Machines, of which the following is a specification. p

This invention. relates to combing machines and is especially concerned with machines of this type designed to handle long stapledwool or similar material.

The machines of this type in common use are-opento the objection that they aretrelativ'ely complicated inconstruction, have a comparatively smalloutput', are very the chief object of the present invention to overcome these objections. 'In other words,

The nature'of the invention Wlllbe readily understoodfrom the V-following description when read in connection with the ac C-ompanying drawings, and the novel featureswill be particularly pointed out in the Referring now to the drawings,

Figure 1 's aside elevation of the more important parts of a combing machine constructed in accordance with this invention; Fig. 2 is a view'simila-r to.F 1g-. 1 showing the parts in a different position; and

3 is another view showing the-manner in which the material is handled at one point in the cycle of the operation of the machine. i

The construction shown comprises a needle or comb segment '2 mounted on a main shaft 3 supported in suitable bearings. Keyed to this shaft is an eccentric 4 which drives an eccentric strap 5 havingan arm 6 projecting upwardly therefrom. This arm has a bolt and slot connection withone arm 7 of a bell crank lever secured fast to the rock shaft 8 by means ofa set screw 9. The

nipper 'fr'ame is mounted fast on this shaft and comprises a lever 10, to the forward end of which the upper nipper '12 is secured. The lowernipper 14;.is mounted on the forward arm of a lever 15 which isfulcrumed on a stud 16 carried by .thenipper lever 10,

the lever 15 having a long helical spring 17 secnred'to its rearward'endwhich acts normallytohold the lower nipper in contact The machine also includes; detachingmechanism comprising flflute'd rolls 20 and 21 mounted on a'levertor arm 22 which is rocksha ft 23 189.11'31111 24: having a long slot 25 -therein. This arm overlaps a link 26 pivoted to the rearward arm 27' of the bell crank lever- 7 previously referred to.

The connection between the parts 24 and 26 includes a [bolt or stud 28 which passes through the slot- 25 so that the relationship between: these two. parts can besadjusted.

It will nowbe appreciatedthat as the ec-,

centric. .4 rotates, thus moving the arm 6 up and'down and swinging the nipper frame in' the manner above described, movement willalso' be transmitted throughihexparts 27. 26 and 24L to the detaching frame22, os-

secured to arock shaft 23". 1 Fast on this cillating this frame backward and forward about the axis of the shaft 23. v a The detaching rolls 20 and 21 are geared together, the gear on the lower roll 21 being.

shown in Fig. 'l at 30. This gear meshes with another gear 31, drivenby a gear 32 which rotates on the-shaft 23 and is driven by a change gear 33 mounted on a shaft 34. The

shaft 34 is drivenby a gear 35 from another gear 36 fast on the main shaft 3. This mechanism thus permits the driving of thedetacliing rolls at any desired speed,- It

should be noted also that due to the bacle.

It will'be'obse-rved engage the tuft ofmaterial to be combed and perform '{the primary combing operation,

while the shorter teeth later engage this tuft of materialandwsubject it to a very gentle secondary combing;

As the detachingrolls are swung toward theinipper frame the part ofthe web which hangs: down behind the rolls isi brought againstthe: side ofth'e web. pan 45', as best shown in Fig. 2,th'e. end 'of the newly de livered tuft-V being laid uponsthe upper part of this portion of the web. The overlapping effected in this manner results in producing a very uniform web'of combed'material. This combedweb is drawn away from the detaching rollby additional rolls 46 and 47 which pull it through the funnel 48, thus forming a sliver which as usual in machines ofthis type.

Attention is particularly called to the fact thatthe swinging movement of the nipper mechanism may be adjusted through the'bolt and slotconnection between the eccentric and the lever 7. Likewisethe swinging movement of the detaching mechanism may be adjusted independently of the movement of the nipper frame by in the slot 25. nipper rolls also can be adjusted to suit exist ing conditions bychanging the gear 33, as

during this backward movement. This combing operation is completed before drops into a coiler,

adjusting the stud 28 1 The speed of'rotation oft'he delivering member, namely, the eccentric 4:, provides a very simple construction and enables the machine to operate very smoothly. This reduces the depreciation and thenecessity for repairs. At the same time the nature of the driving mechanisms for the nipperand detaching frames and the detaching rolls substantially increases the output of the machine. I v. 7 2 j v 1 i YVhile I have herein. shown and described the best embodiment of the invention, of which. I am at present aware, it willbe appreciated that this embodiment may be modified inmany particulars: without departing from the spirit or scopeof this invention.
